DynamicLayoutInflater

Layout inflater with String as source of layout

Overview

Allows to inflate layout from remote source (e.g. backend)

Installation

Add dependency to your build.gradle file:

dependencies {
    implementation 'xyz.truenight.dynamic:inflater:1.0.2'
    // for AppCompat support implementation 'xyz.truenight.dynamic:compat:1.0.2'
}

or to your pom.xml if you're using Maven:

<dependency>
  <groupId>xyz.truenight.dynamic</groupId>
  <artifactId>inflater</artifactId>
  <version>1.0.2</version>
  <type>pom</type>
</dependency>

Usage

Creating base instance

DynamicLayoutInflater like LayoutInflater uses Prototype pattern.

  // creating base instance which will be accessed via ``WeakReference`` 
  // so you need to store strong reference on object returned from create()
  // use CompatDynamicLayoutInflater for AppCompat support
  inflater = DynamicLayoutInflater.base(this)
                .registerAttrAdapter(...)
                .registerParamAdapter(...)
                ...
                .create();

Inflate

  View view = DynamicLayoutInflater.from(context).inflate(resource, parent);

Register AttrAdapter

  inflater = DynamicLayoutInflater.base(this)
          .registerAttrAdapter(ImageView.class, "android:src", new AttrAdapter<ImageView>() {
                @Override
                public boolean apply(final ImageView view, final String value) {
                    if (Utils.startsWith(value, "http")) {
                        imageFromUrl(view, value);
                        // handeled
                        return true;
                    }
                    // not handeled, less priority adapters can try to handle this
                    return false;
                }
           })
           .registerAttrAdapter(View.class, "android:background", new AttrAdapter<View>() {
                @Override
                public boolean apply(final View view, final String value) {
                    if (Utils.startsWith(value, "http")) {
                        backgroundFromUrl(view, value);
                        return true;
                    }
                    return false;
                }
            })
            .create();
